FIELD

The present disclosure generally relates to machine translation and, more particularly, to techniques for automatically swapping languages and/or content for machine translation.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

Machine translation typically involves a source text being translated (the source) and a translated text (the target). Associated with these texts are source and target languages, respectively. A user may specify the source text and the target language and request a machine translation of the text from its source language to the target language. The source language may be specified or, alternatively, may be automatically detected. The user may incorrectly specify the source language and/or the target language, and they may not realize their mistake until after typing at least a portion of the source text. Such errors can cause inaccurate or entirely incorrect machine translations.

It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

BRIEF DESCRIPTION OF THE DRAWINGS

The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:

FIG. 1 illustrates a diagram of a computing network including an example server according to some implementations of the present disclosure;

FIG. 2 illustrates a functional block diagram of the example server of FIG. 2;

FIGS. 3A-3E illustrate example machine translation user interfaces according to some implementations of the present disclosure; and

FIG. 4 illustrates a flow diagram of an example technique for automatically swapping languages and/or content for machine translation according to some implementations of the present disclosure.

DETAILED DESCRIPTION

As previously mentioned, a user may incorrectly specify a source language and/or a target language when requesting machine translation of the source text. Swap functions may enable the user to swap or switch the languages and/or the texts, but problems can emerge when (i) the translated text has not yet been obtained or fully processed, such as due to computer network delays or typing delays or interruptions by the user inputting the source text and (ii) the reverse translation does not have an identity match with the original text (e.g., the translated text has multiple reverse translations back into the source language).

Accordingly, techniques are presented for automatically swapping languages and/or content for machine translation. These techniques are aimed to behave in a manner in which the user would expect. More particularly, when a swap or switch occurs, the user would expect that the source and target languages would swap as well as the content of the texts. The techniques can be implemented at a server, which can detect whether the source and target languages should be swapped using any suitable language models. The server can be configured to output machine translation user interfaces to a requesting computing device.

In some cases, swapping the languages and/or content may be inappropriate. For example, during user typing swapping the content may be inappropriate because this could cause the currently typed text to be overwritten. A static state, however, may be suitable for swapping both the source and target languages and the content. Another example scenario where swapping the languages may be inappropriate is when auto-detection of the source language is enabled. In these scenarios, there is less confidence regarding the accuracy of the source and target languages and thus swapping of the source and target languages should not occur.

When the need for a swap is detected, the server can swap the source and target languages and perform machine translation of the text from the target language (a modified source language) to the source language (a modified target language). Different rules/thresholds can be implemented for swap detection. For example, confidence scores and thresholds may be utilized to determine when to automatically swap the source and target languages. These confidence scores can include a confidence score for the source language as well as confidence score(s) for other languages, such as the target language and/or another specific language or all other languages.

Referring now to FIG. 1, a diagram of a computing network 100 including an example server 104 according to some implementations of the present disclosure is illustrated. The term “server” as used herein can refer to both a single hardware computer server and multiple hardware computer servers operating in a parallel or distributed architecture. The server 104 can communicate with a computing device 108 via a network 112. Examples of the computing device 108 include a desktop computer, a laptop computer, a tablet computer, and a mobile phone. The network 112 can include a local area network (LAN), a wide area network (WAN), e.g., the Internet, or a combination thereof.

While a single computing device 108 is shown, it should be appreciated that the server 104 can similarly communicate with other computing devices. The computing device 108 can represent a computing device requesting machine translation from the server 104. Specifically, a user 116 associated with the computing device 108 can provide a machine translation input to the computing device 108, which can then be transmitted to the server 104. The machine translation input can include (i) a source text, (ii) a source language of the source text, and (iii) a target language for the source text. In response to this machine translation input, the server 104 can provide the computing device 108 a translated text in the target language.

In one implementation, the user 108 can provide the machine translation input via a user interface 120 of the computing device 108. Examples components of the user interface include a physical keyboard 124, a mouse 128, and a display 132, such as a touch display. The computing device 108 can detect when the source text is currently being input and transmit a typing status to the server 104. The server 104 can use this typing status as part of the techniques of the present disclosure. The term “typing status” as used herein can refer to any indication that the source text is currently being input, which could include input not via the physical keyboard 128 (e.g., input via the mouse 128 or via a virtual keyboard on the display 132).

Referring now to FIG. 2, a functional block diagram of the example server 104 is illustrated. The server 104 can include a communication device 200, a processor 204, and a memory 208. The communication device 200 can include any suitable components (e.g., a transceiver) configured for communication with other devices, such as the computing device 108, via the network 112. In some implementations, machine translation can be performed at a one or more separate machine translation servers that are in communication with the server 104 via the network 112 and the communication device 200. The server 104 can then utilize these machine translation(s) as part of the techniques of the present disclosure.

The processor 204 can control operation of the server 104. Example functions performed by the processor 204 include, but are not limited to, loading/executing an operating system of the server 104, controlling communication via the communication device 200, and controlling read/write operations at the memory 208. The memory 208 can be any suitable storage medium (flash, hard disk, etc.) configured to store information at the server 104. The term “processor” as used herein can refer to both a single processor and multiple processors operating in a parallel or distributed architecture. The processor 204 can also perform at least a portion of the techniques of the present disclosure, which are now described in greater detail below.

Referring now to FIG. 3A-3E and with continued reference to FIGS. 1-2, example machine translation user interfaces 300 a, 300 b, 300 c, 300 d, and 300 e (collectively “machine translation user interfaces 300”) are illustrated. While generally shown, each of the machine translation user interfaces 300 could be displayed at the display 132 of the computing device. For example only, the machine translation user interfaces 300 may be displayed in web browser software executing on the computing device 108 as part of a web-based machine translation interface.

Each machine translation user interface 300 includes a source text area 304 and a target text area 308. The source area 304 can receive and display the source text that the user 116 is requesting to have machine translated to a target language. The target area 308 opposes the source area 304 (side-by-side, one on top of the other, etc.) and displays the results of the machine translation, i.e., the translated text. A source language area 312 proximate to the source area 304 can receive and display the source language, and a target language area 316 proximate to the target area 308 can receive and display the target language. For example, the source text area 304 and the source language area 312 may be collectively referred to as the “source area,” and the target text area 308 and the target language area 316 may be collectively referred to as the “target area.”

In the machine translation user interface 300 a of FIG. 3A, the source text area 304 includes the source text “ven” and the source language area 312 specifies English as the source language. The target text area 308 includes the translated text “ven” and the target language area 316 specifies Spanish as the target language. In this case, the translated text can be the same as the source text for a variety of reasons. For example, the machine translation of the source text may not have been provided from the server 104 yet due to processing and/or network delays. Alternatively, for example, the user 116 could still be providing the source text as indicated by the typing status provided to the server 104 by the computing device 108. In these types of scenarios, the translated text can be set to the source text by default. If the typing status is static (e.g., indicative of the source text not currently being input at the computing device 108), the server 104 can determine whether to swap the source and target languages.

The server 104 can utilize any suitable language models to determine whether to swap the source and target languages. For example, the server 104 may use the source text and one or more language models related to the source language to determine whether to swap the source and target languages. The one or more language models may include source language model(s), target language model(s), and/or other language models. In one implementation, the server 104 can calculate a source confidence score that is indicative of a degree of likelihood that the source text is in the source language. In the machine translation user interface 300 a of FIG. 3A, the source confidence score is relatively low (e.g., ˜30%) for reliably determining that the source text “ven” is in English. The server 104 can determine whether to swap the source and target languages based on a comparison between the source confidence score and a source confidence score threshold indicative of high degree of likelihood that the source text is in the source language.

In FIG. 3B, the source confidence score is below any suitable source confidence score threshold and thus the server 104 may determine not to swap the source and target languages. At each of these stages, the server 104 can also determine the translated text in a similar fashion using language models and probabilities. In some implementations, the server 104 can also calculate a target confidence score indicative of a degree of likelihood that the source text is in the target language and determine whether to swap the source and target languages based on a comparison between the target confidence score and at least one of (i) the source confidence score and (ii) a target confidence score threshold indicative of high degree of likelihood that the source text is in the target language. This determination could be further based on comparisons to confidence scores for other specific languages or all other languages.

The source and target confidence score thresholds can be indicative of an acceptable likelihood that a corresponding language is the source or target language, respectively. In other words, these confidence score thresholds represent a high degree of likelihood such that the decision can be reliably made as to whether to swap the source and target languages. The confidence score thresholds could be predetermined, they could be learned using machine learning, they could be set by one or more users, or they could obtained in any other suitable manner. In FIG. 3B, the target confidence score is also relatively low (e.g., ˜65%) for determining that the source text “ven” is in Spanish. The reliability of the target confidence score could be further analyzed by comparing it to confidence score(s) for other specific languages or all other languages. In FIG. 3B, a confidence score for all other languages is very high (e.g., ˜80%), and thus the server 104 can determine not to swap the source and target languages—at least not at this time.

In the machine translation user interface 300 c of FIG. 3C, the source text area 304 includes the source text “veni” and the target text area 308 includes the translated text “veni.” Provided the typing status is static, the server 104 can again determine whether to swap the source and target languages. The source confidence score is relatively low (e.g., ˜30%), while the target confidence score and a confidence score for Romanian are both very high (e.g., 90% and 95%, respectively). Nonetheless, because of the uncertainty of the target language being the correct language for the source text, the server 104 can determine not to swap the source and target languages. Similarly, in FIG. 3D, the source text area includes the source text “venim” and the target text area 308 includes the translated text “Venim.” The confidence scores are again not reliable enough to justify the server 104 swapping the source and target languages. The translated text may be capitalized due to a spell checking function or an assumption that the source text is a proper name that should be capitalized.

In the machine translation user interface 300 d of FIG. 3D, the source text area 304 includes the source text “venimos” and the target text area 308 includes the translated text “Venimos.” For example, the translated text may have remained capitalized from earlier. Provided the typing status is static, the server 104 can again determine whether to swap the source and target languages. In this example, the target confidence score is extremely high (e.g., ˜100%) and the other confidence scores are very low. Therefore, the server 104 can swap the source and target languages automatically in response to this determination. It should be noted that a swap of the source and languages could also have been manually initiated at any time by selection of a selectable swap option 320. As previously discussed, however, when swapping the source and target languages, the user 116 would expect that the underlying content would also be swapped.

More specifically, the server 104 can swap the source and target languages to obtain modified source and target languages. In this example, the modified source language can be the target language (Spanish) and the modified target language can be the source language (English). The server 104 can then utilize the translated text as a modified source text. The server 104 can then obtain a machine translation of the modified source text (“Venimos,” or rather “venimos”) from the modified source language (Spanish) to the modified target language (English) to obtain a translated modified source text “we come.” The server 104 can then output the translated modified source text to the computing device 108. Receipt of the translated modified source text can cause the translated modified source text (“we come”) in the target text area 308 opposing the source text area 304 displaying the modified source text (“venimos”).

In the machine translation user interface 300 e of FIG. 3E, the source text area 304 is shown to include the modified source text “venimos” and the target text area 308 is shown to include the translated modified source text “we come.” Similarly, the source language area 312 is shown as specifying the modified source language “Spanish” whereas the target language area 316 is shown as specifying the modified target language “English.” In situations where the language swap occurs, the server 104 may also output a selectable reset option 324 that can be selected to view the machine translation of the original source text (“venimos”) from the original source language (English) to the target language (Spanish), which was “Venimos.” This selectable reset option 324 could be selected by the user 116 when an incorrect or undesired language swap occurs. For example, an undesired language swap could occur when the original source text is a proper name or another unique word that is not in conventional dictionaries or recognized by conventional language models. In FIG. 3E, and for example only, selecting the selectable reset option 324 could cause the machine translation user interface 300 d of FIG. 3D to be output and displayed by the computing device 108.

Referring now to FIG. 4, a flow diagram of an example technique 400 for automatically swapping languages and/or content for machine translation according to some implementations of the present disclosure is illustrated. At 404, the server 104 can receive, from the computing device 108, a machine translation input specifying (i) a source text, (ii) a source language of the source text, and (iii) a target language for the source text. At 408, the server 104 can obtain a machine translation of the source text from the source language to the target language to obtain a translated source text. This translated source text may be obtained at the server 104 or obtained by the server 104 from another server.

At 412, the server 104 can output the translated source text to the computing device 108, thereby causing the computing device 108 to display the translated source text in the target text area 308 opposing the source text in the source area 304. At 416, the server 104 can determine whether to swap the source and target languages. If the source and target languages should not be swapped, the technique 400 can end or return to 404 for one or more additional cycles. If the source and target languages should be swapped, however, the technique 400 can proceed to 420. At 420, the server 104 can swap the source and target languages to obtain modified source and target languages.

At 424, the server 104 can obtain a modified source text, such as by utilizing the translated source text as the modified source text. At 428, the server 104 can obtain a machine translation of the modified source text from the modified source language to the modified target language to obtain a translated modified source text. At 432, the server 104 can output, to the computing device 108, the translated modified source text, thereby causing the computing device 108 to display the translated modified source text in the target area 308 opposing the modified source text in the source area 304. The technique 400 can then end or return to 404 for one or more additional cycles.

A computer-implemented method, comprising: receiving, at a server from a computing device, a machine translation input specifying (i) a source text, (ii) a source language of the source text, and (iii) a target language for the source text; obtaining, at the server, a machine translation of the source text from the source language to the target language to obtain a translated source text; determining, at the server, whether to swap the source and target languages based on (i) the source text, (ii) a confidence score for the translated source text, and (iii) at least one language model, wherein swapping of the source and target languages is disabled when (a) auto-detection of the source language is enabled and (b) a typing status indicates that a user of the computing device is currently typing; and in response to determining to swap the source and target languages: swapping, at the server, the source and target languages to obtain modified source and target languages, utilizing, at the server, the translated source text as a modified source text, obtaining, at the server, a machine translation of the modified source text from the modified source language to the modified target language to obtain a translated modified source text, and outputting, from the server to the computing device, the translated modified source text.
 2. The computer-implemented method of claim 1, further comprising outputting, from the server to the computing device, the translated source text, wherein receipt of the translated source text causes the computing device to display the translated source text in a target area opposing a source area displaying the source text.
 3. The computer-implemented method of claim 2, wherein receipt of the translated modified source text causes the computing device to display the translated modified source text in the target area opposing the source area displaying the modified source text.
 4. The computer-implemented method of claim 3, further comprising outputting, from the server to the computing device, a selectable reset option to view the machine translation of the source text from the source language to the target language.
 5. The computer-implemented method of claim 4, further comprising: receiving, at the server from the computing device, a selection of the selectable reset option; and in response to receiving the selection, outputting, from the server to the computing device, the translated source text, wherein receipt of the translated source text causes the computing device to display the translated source text in the target area opposing the source area displaying the source text.
 6. The computer-implemented method of claim 1, wherein determining to swap the source and target languages further comprises: calculating, at the server, a source confidence score, the source confidence score indicative of a degree of likelihood that the source text is in the source language; and determining, at the server, whether to swap the source and target languages based on a comparison between the source confidence score and a source confidence score threshold indicative of high degree of likelihood that the source text is in the source language.
 7. The computer-implemented method of claim 6, wherein determining whether to swap the source and target languages further includes: calculating, at the server, a target confidence score, the target confidence score indicative of a degree of likelihood that the source text is in the target language; and determining, at the server, whether to swap the source and target languages based on a comparison between the target confidence score and at least one of (i) the source confidence score and (ii) a target confidence score threshold indicative of high degree of likelihood that the source text is in the target language.
 8. The computer-implemented method of claim 1, further comprising: outputting, from the server to the computing device, a selectable swap option to view the machine translation of the source text from the target language to the source language; receiving, at the server from the computing device, a selection of the selectable swap option; and in response to receiving the selection, determining, at the server, to swap the source and target languages.
 9. A server having one or more processors configured to perform operations comprising: receiving, from a computing device, a machine translation input specifying (i) a source text, (ii) a source language of the source text, and (iii) a target language for the source text; obtaining a machine translation of the source text from the source language to the target language to obtain a translated source text; determining whether to swap the source and target languages based on (i) the source text, (ii) a confidence score for the translated source text, and (iii) at least one language model, wherein swapping of the source and target languages is disabled when (a) auto-detection of the source language is enabled and (b) a typing status indicates that a user of the computing device is currently typing; and in response to determining to swap the source and target languages: swapping the source and target languages to obtain modified source and target languages, utilizing the translated source text as a modified source text, obtaining a machine translation of the modified source text from the modified source language to the modified target language to obtain a translated modified source text, and outputting, to the computing device, the translated modified source text.
 10. The server of claim 9, wherein the operations further comprise outputting, to the computing device, the translated source text, wherein receipt of the translated source text causes the computing device to display the translated source text in a target area opposing a source area displaying the source text.
 11. The server of claim 10, wherein receipt of the translated modified source text causes the computing device to display the translated modified source text in the target area opposing the source area displaying the modified source text.
 12. The server of claim 11, wherein the operations further comprise outputting, to the computing device, a selectable reset option to view the machine translation of the source text from the source language to the target language.
 13. The server of claim 12, wherein the operations further comprise: receiving, from the computing device, a selection of the selectable reset option; and in response to receiving the selection, outputting, to the computing device, the translated source text, wherein receipt of the translated source text causes the computing device to display the translated source text in the target area opposing the source area displaying the source text.
 14. The server of claim 9, wherein determining to swap the source and target languages further comprises: calculating a source confidence score, the source confidence score indicative of a degree of likelihood that the source text is in the source language; and determining whether to swap the source and target languages based on a comparison between the source confidence score and a source confidence score threshold indicative of high degree of likelihood that the source text is in the source language.
 15. The server of claim 14, wherein determining whether to swap the source and target languages further includes: calculating a target confidence score, the target confidence score indicative of a degree of likelihood that the source text is in the target language; and determining whether to swap the source and target languages based on a comparison between the target confidence score and at least one of (i) the source confidence score and (ii) a target confidence score threshold indicative of high degree of likelihood that the source text is in the target language.
 16. The server of claim 9, wherein the operations further comprise: outputting, to the computing device, a selectable swap option to view the machine translation of the source text from the target language to the source language; receiving, from the computing device, a selection of the selectable swap option; and in response to receiving the selection, determining to swap the source and target languages.
